1'm new learner of Perl6, and Inline::Perl5 install failed because the t/p5_object_destructor.t and the t/p6_object_destructor.t tests failed. OS is Linux Mint 19.1 (Ubuntu based). Perl6 V6d. Rakudo Star version 2019.03.01. "zef install" works on other modules. The code for the t/p5_object_destructor.t has the line "use ObjWithDestructor:from<Perl5>;". I cannot find ObjWithDestructor in CPAN. This might be the problem, but it is not required in t/p6_object_destructor.t so the problem might be the something missing in the Mint OS? I am reluctant to use the zef "--force-test" option without informed advice as I suspect it would create a rippling of problems when using Perl5 modules down the track. Any thoughts?
